The German carrier said it will charter slots on the new joint service, which is slated to commence at the end of November.
The two carriers earlier said they would operate the service with six 2,800-TEU vessels, with CMA CGM phasing in five vessels and Argentina-based Maruba, one.
The rotation is Rotterdam, Hamburg, Antwerp, Le Havre, Santos, Montevideo, Buenos Aires, Rio Grande, Itajai, Paranagua, Santos, Tangier and back to Rotterdam, offering a 42-day round-trip voyage.
Senator said the service will provide a transit time of 18 days between Hamburg and Buenos Aires, and 14 days from Santos to Rotterdam.
"After the termination of the K-Line/Maruba/China Shipping consortium in April, 2008 and the general capacity decrease in the market resulting thereof, we take the chance now to increase our capacity into the constantly growing South American market again," Senator stated.
The first vessel under the slot arrangement will be the CMA CGM Violet, currently expected to depart Rotterdam Nov. 28.
